A machine that uses flowing air to turn large blades that power a generator and creates electricity is called a

• A. Windmill
• B. Turbine generator
• C. Wind turbine
• D. Air turbine

Answer: (C)

The main idea is that wind energy is converted into electricity using a wind turbine. In a wind turbine, flowing air pushes the large blades, causing the rotor to spin. This rotation powers a generator inside the machine, which converts the mechanical energy into electrical energy for the grid. Windmills are older devices built to perform mechanical work like grinding grain or pumping water, not primarily to generate electricity. The term turbine generator describes the combo of a turbine driving a generator, but the standard name for the device that makes electricity from wind is wind turbine. An air turbine isn’t a common term for this purpose.
